Vedclass · Answer

(C) Let us analyze the nature of the salts in aqueous solution:$(1)$ $FeCl_3$ is a salt of a strong acid $(HCl)$ and a weak base $(Fe(OH)_3)$. It undergoes cationic hydrolysis to form an acidic solution. Thus,statement $(1)$ is incorrect.$(2)$ $NH_4Cl$ is a salt of a strong acid $(HCl)$ and a weak base $(NH_4OH)$. It undergoes cationic hydrolysis to form an acidic solution. Thus,statement $(2)$ is correct.$(3)$ $NaCN$ is a salt of a weak acid $(HCN)$ and a strong base $(NaOH)$. It undergoes anionic hydrolysis to form a basic solution. Thus,statement $(3)$ is incorrect.$(4)$ $Na_2CO_3$ is a salt of a weak acid $(H_2CO_3)$ and a strong base $(NaOH)$. It undergoes anionic hydrolysis to form a basic solution. Thus,statement $(4)$ is correct.Since statements $(1)$ and $(3)$ are incorrect,the correct option is $C$.

Consider the following aqueous solutions:
$(1)$ $FeCl_3$ is basic
$(2)$ $NH_4Cl$ is acidic
$(3)$ $NaCN$ is acidic
$(4)$ $Na_2CO_3$ is basic
Which of the following statements is $NOT$ correct?
